SPRING-SCALE.

SPECIFICATION forming part of Letters Patent No. 467,496, dated January 26, 1892.

Application filed November 23, 1891- Serial No. 412,737. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN P. GHATILLON,

' a resident of the city, county, and State of side view of the upper carrying-plate.

This invention relates to a new construction of parts constituting the body or casing and load-carrying portion of a spring-scale; and it consists, mainly, of a carrying-piece combined with a stamped casing, said carryingpiece being notched to receive into the notch the upper portion of said casing, as hereinafter more fully described.

In the accompanying drawings, the letter A represents the case proper of the springscale, the same being stamped, by preference, of a single piece of sheet Inetahforming a rounded back a, with rounded ends and flanged sides b. An aperture is formed in the lower part of this case A to admit the follower B, from which the article to be weighed is suspended by means of a hook O or in any other proper manner. The front of the case A is riveted or otherwise connected to a face-plate D, which carries the usual scale, read by a pointer d, that extends through a slot in the face-plate from the follower B. The follower Bis suspended from a spring E, whichin turn is suspended from an upper carrying-plate F, and this in turn from a ring G or analogous contrivance. This upper carrying-plate F has twoperforations, one for the reception of the spring and another for the reception of the ring G. The said upper carrying-plate F also case A and is, when the parts are properly assembled, hammered down to form a rivet,

as is clearly indicated in Fig. 2, the same figure showing that for the reception of the portion of the upper carrying-plate which lies between the notch e and the front edge of said plate the case A is apertured.

The construction of parts hereinabove specified is exceedingly simple and serves to relieve the case A and its face-plate D from any strain occasioned by suspending articles to be weighed from the follower 13.

Having described my invention, I claim 1. In a spring-scale, the upper carryingplate F, having notch e and projection f along its back edge, combined with the casing A, adapted to enter the notch e and to receive the proj eotion f, substantially as herein shown and described.

2. In a spring-scale, the combination of the stamped case A, having rounded central portion a and side flanges b, with the slotted faceplate D, follower B, spring E, and upper carrying-plate F, said upper carrying-plate having notch e to receive the upper part of the case A and projection f, which extends to the case A, the case A being perforated to admit the body of the carrying-plate F, which lies in front of the notch e, and to admit the pro jection f of the carrying-plate, and also to admit the follower B, all as and for the purpose herein shown and described.

JOHN P. CHATILLON.
